The birth of the first internal combustion engine car
1885+00 In June, German Carl Benz (1844 ~ 1929) successfully developed the world's first car, which laid the foundation for car design in one fell swoop, even today's cars can't jump out of this box. On 1886129 October, he applied to the German Patent Office for an automobile invention patent, which was officially approved and published by the Patent Office on12 October of the same year. Therefore,1886 65438+1October 29th is recognized as the birth date of the world automobile, and Ben Ci's patent certificate has also become the first automobile patent certificate in the world.
In fact, before Ben Ci, some people were already developing car engines and cars. The French newspaper reported the car invented by Renault as early as 1863. The speed was less than 8km /h, but it still ran 18km from Paris to Joveriboda. 1884, a Frenchman, Debo Thivel, made a three-wheeled car with a single-cylinder internal combustion engine and a four-wheeled car with a double-cylinder internal combustion engine with the internal combustion engine as the power source.
Long before the invention of the first automobile, there were many related inventions, such as lead-acid battery, ignition device of internal combustion engine, hard rubber solid tire, spring suspension and so on, so the automobile is a comprehensive application of many inventions or technologies.
Gottlieb daimler's four-wheeled vehicle
188 1 year, Daimler cooperated with William Maibakh to open the first so-called automobile factory at that time. 1883 On August 5th, Daimler and Maibakh invented the gasoline internal combustion engine. At the end of 1885, Daimler modified the carriage, added steering and transmission devices, installed an internal combustion engine with the power of 1. 1kw, and installed four wheels, and the speed reached14.4 km/h.
1885, German gottlieb daimler (1843 ~ 1900) invented the first four-wheel car. Ben Ci and Daimler are recognized as the inventors of modern cars driven by internal combustion engines. Their inventions became the most important milestone in the history of automobile development, so they were honored as "the father of automobiles" by the world.
